It appears to me that the authzIds-are-not-necessarily-DNs notion will cause a ripple of change through the protocol and information model. The introduction of authzid representation [AuthMeth] will lead to creatorsAuthzid, modifiersAuthzid, memberAuthzid, and many other use of DNs to be replaced with something that can contain both an authzId. I believe the addition of authzIds will unnecessarily complicate the protocol and information model.
